Improvements in Combined Folders" and Binders for Sewing-Machines, ofwhich the following is a description, reference being had to theaccompanying drawing and to the figures of reference marked thereon.

My invention relates tonew and useful improvements in sewing machinesand more particularly to acomblned folder and binder for guiding. andbinding the overlapped meeting edges of' sections of fabric.

An'object of the inventlon is to "provlde a sewing machine'having atubular work sup ort and a folder for directing the. edges .of' arbricsections which are tobe joined to form 'a tubular article withoutfolding 'theinner edge with a binder for directing a. binding stripabout the inner edge, so that said binding needles joining the edges ofthe fabric sections.

provide a combined folder and binder of the above character, wherein thefolder is so mounted that it may be moved away from the binder tofacilitate'the insertion of the binding strip to the binder. y

A further object of the invention" is to provide a sewing machine forstitchingn1sm; g

Cooperating with the stitching mechanism is a feeding mechanism, whichfeeds the overlapped sections on to the work supporting arm for thestitching operation. Located in advance of the stitching mechanism is acombined folder and guide, which receives the edges of the fabric whichis to be stitched into a tubular article. This combined folder and guideis shaped so as unfolded edge, so that when the stitchingmechanismoperates upon the fabric edges and the binding strip, one of the needlespenetrates said fabric adjacent the fold in the upper edge thereof, and.the other needle penetrates both fabric edges and adjacent the inneredges ofthe binding strip.

Also cooperating with J the binder is a guide which extends parallelwith the worksupporting arm, so that when a tubular article, is beingstitched the binding strip passing through this guide to the binder willbe led to the inner face of the tubular article and bind the plain orunfolded edge on the inner face of said tubular article.

Referring more in detail to the drawings,

I have shown my invention applied to a sewing machine consisting of asupporting bed 1 having a standard 2 carrying an over-- hanging arm 3.Also carried by the standard and projecting therefrom is a tubular worksupport 4. This tubular work support projects underneath the free end ofthe overhanging arm. Located within the tubular work support is afeeding mechanism including a feed dog 5 (see Fig. 6), which is sodisposed as to feed the material being stitched lengthwise of thetubular work-supporting arm. The feeding mechanism is so constructed asto feed the material in the direction of the arrow Fig. 6, or onto the'work-supporting arm during the stitching operation. 'After the tubulararticle has been thus formed, it is withdrawn from the arm. This generaltype of machine and method of stitching tubular articles are well knownin the art, and further description thereof i not thought necessary.

,In the forward'end of the overhanging arm 3 is a needle bar 6, whichcarries two needles 7 and 8. The needle bar is reciprocated by a needlelever 9, connected to the needle bar by means of the link 10. Extendingthrough the standard 2 is a main shaft 11, provided with a belt wheel12. 'On this main shaft is a suitable eccentric with which an eccentricstrap 13 cooperates, and this which carries a folder.

supporting armand cooperates with the feed dog 5 in the feeding of thefabric being stitched.

Cooperatin g with the needle 7 beneath the work supportis a looper 16,while cooperating with the needle 8 beneath the work support is a looper17. These loopers are mounted on a looper-carrier 18, attached to ashaft extending lengthwise of the tubular work-supporting arm, and thisshaft is actuated through suitable connections with the main shaft 11.

Directly in front of the stitching mechanism is a folder 19. Locatedbetween the folder 19 and the needles is a binderv 20. This binder is,as above noted, of the English binder type, and is adapted to receivestrip guide 21, which extends parallel with the work-supporting arm 4,and to a point in rear of the standard 2.

The throat plate 22 (see Fig.4) is provided with a forwardly extendingportion 23, which extends beyond the front end of the worksupportingarm. This extension v has a recess adapted to'reoeivef aslide 24,

The folder is secured to the slide by suitable screws 25 and the slideis secured to this extension by a screw 26 which. passes down through aslot 26 extending lengthwise of the extension,

This slide 24 is formed with a thumb piece orh'andle, whereby it may bepushed toward. the stitching mechanism, or drawn away from the same.When it is moved up toward the stitching mechanism, then the folder, is

guiding the edges of the fabric eing brought close to the binder forfoldin and stitched. When it is moved away from the binder, then thebinder isexposed, so that the operator may readily direct the bindingstriptherethrough.

The folder has a'fabric-guiding portion 27 (seeFig. 2) and ah edge guide28 for the fabric section which passes over said guidin portion. 27.Said folder is also provide with a second fabric-guiding portion 29 forthe other edge of the fabric-section. to be stitched. The section 29carries afolding edge of the fabric section resting on thefabric-guiding portion 29.

In Fig. 2 of the drawings, I have shown a tubular article indicated at Fbeing guided and stitched. The edge f of the fabric rests upon theguiding portion 27 and is directed by the ed e guide 28. ,This edge ofthe fabric is p am. or unfolded. The other edge of the fabric indicatedat f is, however, bent back upon itself or folded as it is passed to thestitching mechanism.

scroll 30, adapted to receive and fold the dicates needle 7 7 The edge fof the fabric projects slightly beyond the folded-under edge 7. Thebinder is so disposed as to place a binding,

indicated at B, about" this projecting edge This binder is secured f ofthe fabric.

32 which pass to a bracket 31 by screws through slots 33 in a secondbracket 31 con nected to the binder 20. lhis permits the binder to beadjusted transversely of the line of feed.

. The binder is formed with two guiding walls 34 and 35, thus making a U-shaped guiding space. The guiding wall 34 extends about the guidingwall 35 at the lower side thereof, so the lower'edge of the bindingstrip will be folded back, as indicated at b. As the binding strippasses through this binder, it will be folded and the lower edge.thereof will be turned back on the outer face of the'binding strip. Theend of the binder is cutaway at an angle of 45 degrees, as is common inthis type of binder, so this folded binding strip may be inverted tobring the folded back part between the side faces of thebinding strip.The binder is so placed on the machine that when the binding strip isinverted and directed to the stitching mechanism, the needle 8 will passthrough the edges of the binding strip. In Fig. 10 of the drawings,theline n indicates the line of stitching formed by the needle 8, 'whichpasses, down through the upper fabric and through the inner edges of thebinding strip.

The binding strip guide 21 is in the form of a skeleton guiding framewhich extends from a point adjacent the binder to a point at the rear ofthe machine, and this binding strip guide is secured to the machine bysuitable brackets 37 and holding screws 38. The binder 20 is alsoprovided with a guiding extension 39, for guiding the binding after itleaves the binder until it is substantially secured by the needle 8* ofthe stitching mechanism.

The operation of my device will be ap-' parent from the abovedescription. The strip is led through the binding directed through thefolder and guide which folds the upper edge underneath and between thetwo overlapped edges, while the under edge of the fabric is left plainor unfolded. The binding strip is wrapped around this plain or unfoldededge and the needles of the stitching mechanism passing down through theoverlapped edges secure the same together, as above described. Afteredges thereof.

' Letters Patent, is

the tubular article has been stitched, the

presser foot may be raised and the article slipped on from theWork-supporting arm.

While I have shown and described my invention as applied to a sewingmachine for stitchingtubular articles, it will be understood fromcertain aspects of the invention that the combined folding and bindingmechanism may be used in connection with separate fabric sections forjoining [the It will also in the details of construction and arrangementof parts may be made, without departing from the spirit of the inventionas set forth in the appended claims.
